i have the same psu that he has sitting besides me- yeah, the 550w coulours it led was a small price too pay for the much better OCZ stealthxstream - eg:i had to add neon lights into my rig thanks to the lack of led's

It doesn't have two 18A 12V rails, but only one 12V rail delivering 20A when the minimum for the GTX460 is 24A on the 12V rail....

Add that to the efficiency lost due to the PSU being 4 years old...

I'm ready to bet the PSU is the problem.

yeah, that said these are suprisingly good, mine managed to power an oc'd gts 250 and an unlocked 550

@BP behind me are 2 psu's and a case, above my head are the boxes to 2 gfx cards, a few hd and pheripherals, and there are mobo's + cpu's all around our house, we don't throw away anything in our house so we are now up to 6 computers - theres one made entirely out of parts i've stopped using in the last 3 years

hi all sry for the delay got the hoover out and dusted of inside lol yes that is the psu but mine saidon the side +3.3v 28a +5v 35a and the one 12v rail said 30aand is 550watt, but it only has 1 , 6 pin conctor and i had to use a splitterof 2 molex do u all think the psu at fault?

could be your cabling, its a cheap psu which means there probably at minimum specification - 2 molex is technicly 22a so it would seam to be enough with the pci-e slot but you don't know how it was devided at the power supply end

i cant the psu only has one 6 pin and then i used the 2 4 pin molex connectors to a second 6 pin because the gtx 460 needs 2 six pin connectors, i was playing enemy terroity online earlier and for the fist time ever (been playing it for 6 yrs) the frames crashed down from 76 fps to 2 then then i had no signal on screen and had to hard reset pc to get monitor to work said no signal, but when i checked to log on gpuz all temps was ok in thelow 40 degress? do u think its the psu starting to play up? tyvm for taking the time to help martyn
